Numerical and experimental analysis of the effect of forced cooling on laser tube forming

In the laser forming process, a cooling time is usually considered between successive scans to increase temperature gradient and subsequently bending angle. this performed at ambient temperature, which can lead high in operation costs. The rate undesirable changes microstructure depending on type of material. research, by introducing simple method for applying forced with water different distances from beam, its effects are investigated AISI 304L tubes using finite element experiments. angles tube after analyzed. results show that local reduces duration 1-degree bend about 8 13 times compared temperature. However, small offset beam increases residual stress consequently probability corrosion cracking. likelihood intergranular precipitation steel cooling. According results, certain distance least change has efficiencies less chance forming.
